Cannot find the RPM - 026

If square chain is faster than round chain then squaring up the cylinder will be faster than round cylinders...

Round piston in a square cylinder = less friction.

True...less surface contact... this could be revolutionary in the saw industry

Loss of compression sucks.

Compression just makes it harder to turn over right?

Condrum really, makes them easier to start but yes harder to turn over

OEM cylinders are rounder, you still have some don`t cha?

I got some things in a box.....

You have a belt sander and a sharpie?

Just a few right

No belt sander but I do have a 1/4 sheet sander and a carpenters pencil.

1 or 2 things in boxes... and then there are totes, buckets, baskets, and piles.

Better than nothing I guess, a sheet of glass and some self adhesive machine paper will get you there.

Well now, lets get serious. What is your timing numbers Jimmy?

Gotta get a few things off the bench to time it. I was cleaning up while waiting on a few things.

So I finished the boss's project for today...but no progress on the 026. I did do some thinking. By increasing the RPM from 14,100 to 15,500 air flow through the filter increases by 10%. OK that's simple math... 24.399 CFM to 26.836 CFM. Now those numbers seem low until you think about what a shop air compressor moves for air. That is why the choke flap is a major hold back on an 026/260 saw. That's a bunch of air through the little air filter hole. Now that velocity through the carb helps low speed performance on the flip side.

Just ramblings and thoughts.....
